According to Dennis Ritchie and one of the three definitions of "UNIX" it is. I think I'll give Ritchie's opinion on the subject just a little more credence than yours. I generally prefer to say "a UNIX" or "*NIX" to refer to one of these operating systems that isn't UNIX by codebase or certification.
You're simply wrong
Go tell Dennis Ritchie he's wrong about the operating system he wrote and tell me how that went. His definition is even more encompassing than the one I use. Since you are very, very often wrong with me catching you on it (see the recent IBM/Monterey issue), you are just so desperate to catch me in something wrong. It must be frustrating.
There are three generally accepted definitions of the word "UNIX" and not all within them are universally agreed: lineage from Bell, general functionality (looks like a duck) and certification. Just because you prefer the lineage definition does not make you right and me wrong. Sorry, thanks for playing.
Unfortunately for you your absolute hatred blinds you to the complex realities and that constantly trips you up and has you in contradictory positions. That's why you end up with lame arguments, like how you tried to justify giving open source BSD a pass while railing against the supposed national security implications of open source. You paint yourself into a corner.
Dennis Ritchie doesn't own that definition and never did, but I can see why he'd like to put what he percieves as his label on everything imaginable. As for the facts, Linux only meets one of your own three definitions LOL. How hilarious is that? But using them anyway, if you have all three you're bonafide UNIXtm. Two of the three is "Unix". One of the three is wannabe, "Unix-like".

Hardly. Considering your history of admitted lying to protect criminal foreign hackers, constant plugging of foreign products including cheap immitations, and most importantly routine attacks on Republicans and Christians, all by way of distorted facts and double speak, I see you as more of a punching bag.
